The effect of air velocity on slugs in a confined channel
Flow Measurement and Instrumentation, 2021 The present work focuses on the study of slugs occurring in a two-phase flow of a confined rectangular channel: conditions of appearance and effect on the flow behavior. Three-dimensional numerical simulations have been carried out to examine the effect of superficial air velocity on flow behavior.
